Nazi Germany used six extermination camps, also called death camps, or killing centers, in Central Europe, primarily Occupied Poland, during World War II to systematically murder over 2.7 million people – mostly Jews – in the Holocaust. The victims of death camps were primarily murdered by gassing, either in permanent installations constructed for this specific purpose, or by means of gas vans. The six extermination camps were Chełmno, Belzec, Sobibor, Treblinka, Majdanek and Auschwitz-Birkenau. Extermination through labour was also used at the Auschwitz and Majdanek death camps. Millions were also murdered in concentration camps, in the Aktion T4, or directly on site.
Karl Brandt was a German physician and Schutzstaffel (SS) officer in Nazi Germany. Trained in surgery, Brandt joined the Nazi Party in 1932 and became Adolf Hitler's escort doctor in August 1934. A member of Hitler's inner circle at the Berghof, he was selected by Philipp Bouhler, the head of Hitler's Chancellery, to administer the Aktion T4 euthanasia program. Brandt was later appointed the Reich Commissioner of Health and Emergency Services. Accused of involvement in human experimentation and other war crimes, Brandt was indicted in late 1946 and faced trial before a U.S. military tribunal along with 22 others in the Doctor's Trial. He was convicted, sentenced to death, and hanged on 2 June 1948.
A gas chamber is an apparatus for killing humans or other animals with gas, consisting of a sealed chamber into which a poisonous or asphyxiant gas is introduced. Poisonous agents used include hydrogen cyanide and carbon monoxide.
Aktion T4 was a campaign of mass murder by involuntary euthanasia in Nazi Germany. The term was first used in post-war trials against doctors who had been involved in the killings. The name T4 is an abbreviation of Tiergartenstraße 4, a street address of the Chancellery department set up in early 1940, in the Berlin borough of Tiergarten, which recruited and paid personnel associated with Aktion T4. Certain German physicians were authorised to select patients "deemed incurably sick, after most critical medical examination" and then administer to them a "mercy death". In October 1939, Adolf Hitler signed a "euthanasia note", backdated to 1 September 1939, which authorised his physician Karl Brandt and Reichsleiter Philipp Bouhler to begin the killing.
Viktor Hermann Brack was a member of the Schutzstaffel (SS) and a convicted Nazi war criminal and one of the prominent organisers of the involuntary euthanasia programme Aktion T4; this Nazi initiative resulted in the systematic murder of 275,000 to 300,000 disabled people. He held various positions of responsibility in Hitler's Chancellery in Berlin. Following his role in the T4 programme, Brack was one of the men identified as responsible for the gassing of Jews in extermination camps, having conferred with Odilo Globočnik about its use in the practical implementation of the Final Solution. Brack was sentenced to death in 1947 in the Doctors' Trial and executed by hanging in 1948.
Christian Wirth was a German SS officer and leading Holocaust perpetrator who was one of the primary architects of the program to exterminate the Jewish people of Poland, known as Operation Reinhard. His nicknames included Christian the Cruel, Stuka, and The Wild Christian due to the extremity of his behaviour among the SS and Trawniki guards and to the camp inmates and victims.
Karl Ludwig Lorenz Binding was a German jurist known as a promoter of the theory of retributive justice. His influential book, Die Freigabe der Vernichtung lebensunwerten Lebens, written together with the psychiatrist Alfred Hoche, was used by the Nazis to justify their T-4 Euthanasia Program.
The Hadamar killing centre was a killing facility involved in the Nazi involuntary euthanasia programme known as Aktion T4. It was housed within a psychiatric hospital located in the German town of Hadamar, near Limburg in Hessen.
Horst Schumann was an SS-Sturmbannführer (major) and medical doctor who conducted sterilization and castration experiments at Auschwitz and was particularly interested in the mass sterilization of Jews by means of X-rays.
Philipp Bouhler was a German senior Nazi Party functionary who was both a Reichsleiter and Chief of the Chancellery of the Führer of the NSDAP. He was also the SS official responsible for the Aktion T4 euthanasia program that killed more than 250,000 disabled adults and children in Nazi Germany, as well as co-initiator of Aktion 14f13, also called Sonderbehandlung, that killed 15,000–20,000 concentration camp prisoners.
Ewald Meltzer was a German director of an asylum in Saxony whose work was used by the Nazis to justify their T-4 Euthanasia Program.
Erwin Hermann Lambert was a German perpetrator of the Holocaust. In profession, he was a master mason, building trades foreman, Nazi Party member and member of the Schutzstaffel with the rank of SS-Unterscharführer (corporal). He supervised construction of the gas chambers for the Action T4 euthanasia program at Hartheim, Sonnenstein, Bernburg and Hadamar, and then at Sobibór and Treblinka extermination camps during Operation Reinhard. He specialized in building larger gas chambers that killed more people than previous efforts in the extermination program.
The two Treblinka trials concerning the Treblinka extermination camp personnel began in 1964. Held at Düsseldorf in West Germany, they were the two judicial trials in a series of similar war crime trials held during the early 1960s, such as the Jerusalem Adolf Eichmann trial (1961) and the Frankfurt Auschwitz Trials (1963–65), as a result of which the general public came to realize the extent of the crimes that some two decades earlier had been perpetrated in occupied Poland by German bureaucrats and their willing executioners. In the subsequent years, separate trials dealt with personnel of the Bełżec (1963–65), Sobibor (1966), and Majdanek (1975–81) extermination camps.
Action 14f13, also called Sonderbehandlung14f13 and Aktion 14f13, was a campaign by Nazi Germany to murder Nazi concentration camp prisoners. As part of the campaign, also called invalid or prisoner euthanasia, the sick, the elderly and those prisoners who were no longer deemed fit for work were separated from the rest of the prisoners during a selection process, after which they were murdered. The Nazi campaign was in operation from 1941 to 1944 and later covered other groups of concentration camp prisoners.
Alfred Erich Hoche was a German psychiatrist known for his writings about eugenics and euthanasia.
The Sonnenstein Euthanasia Clinic was a Nazi killing centre located in the former fortress of Sonnenstein Castle near Pirna in eastern Germany, where a hospital had been established in 1811.
The Hartheim killing centre was a killing facility involved in the Nazi programme known as Aktion T4, in which German citizens deemed mentally or physically unfit were systematically murdered with poison gas. Often, these patients were transferred from other killing facilities such as the Am Spiegelgrund clinic in Vienna. This was initially a programme of "involuntary euthanasia" permitted under the law ostensibly to enable the lawful and painless killing of incurably ill patients; these murders continued even after the law was rescinded in 1942. Other victims included Jews, Communists and those considered undesirable by the state. Concentration camp inmates who were unfit for work, or otherwise deemed troublesome, were also executed here. The facility was housed in Hartheim Castle in the municipality of Alkoven, near Linz, Austria, which now is a memorial site and documentation centre.
The Brandenburg Euthanasia Centre, officially known as the Brandenburg an der Havel State Welfare Institute, was a killing centre established in 1939 as part of the Nazi euthanasia programme, known after the war as "Aktion T4". Nearly 10,000 people were murdered there during its operation, primarily those with mental and physical disabilities.
The Nazi Euthanasia Centre at Bernburg operated from 21 November 1940 to 30 July 1943 in a separate wing of the State Sanatorium and Mental Hospital in Bernburg on the River Saale in the German state of Saxony-Anhalt. It was one of several euthanasia centres run by the Nazis under their official "Euthanasia Programme", later referred to after the war as Action T4. A total of 9,384 sick and handicapped people from 33 welfare institutions and nursing homes as well as around 5,000 prisoners from six concentration camps were killed there in a gas chamber using carbon monoxide gas.
